Srimad Bhagavatam 1.3.38

The Lord, who wields the discuss, has infinite power and prowess, no one can find its limit. Even though he has created the entire world, he transcends it. His true form and his pastimes, the secret of both of these can only be known by one who relentlessly, with no malice, imbibes the perfume of His lotus feet, which means, always contemplates his feet || 38 ||
